BACKGROUND

Computing devices are becoming increasingly more prevalent in the modern world. In particular, it is not uncommon for a single user to own more than one mobile device or possibly utilize multiple devices throughout their daily lives. For example, a single user may own a smartphone device to manage their personal contacts and communications. Further, the user may operate a laptop computer or a desktop computer in a work environment. Yet further, the user may also own or operate a tablet computer in their home, possibly for a home entertainment system, among other possibilities.

As users become increasingly more dependent on their mobile devices, the users may also become increasingly more reliant on the batteries of their mobile devices. For example, it may be undesirable to a user to have to charge their mobile device more than once a day. Yet further, in some instances, it may be undesirable to have to charge the mobile device more than once in a few days or in a week, possibly depending on the usage of the device. Notably, a mobile device with a shorter battery life may leave users unsatisfied as they may face various inconveniences. For example, a user may be forced to regularly carry a charger to help ensure that the mobile device may be charged when the battery level of the device becomes lower than the level that is desired. Further, the user may be forced to look for charging stations on a frequent basis to charge the device, among other inconvenient scenarios possibly related to regularly changing the battery of the device.

In various respects, designers of such mobile devices often face several challenges in developing architectures that may optimize the battery life of a mobile device. For example, improving the battery life of a mobile device may be costly, particularly if the architecture requires more board space, circuitry, and/or hardware components. Further, improving the battery life of the mobile device may compromise other aspects of the mobile device, possibly creating design and/or technical issues, thereby delaying time to market. As such, there may be several challenges to optimizing the power management of the mobile device.

As demonstrated above, there is much need for technological advancements in various aspects of mobile device architectures and related technologies associated with managing the power of a mobile device.

DETAILED DESCRIPTION

Example embodiments described herein provide various aspects of mobile device architectures and related technologies associated with preserving the power of a mobile device. In practice, consider a scenario where a user is in possession of a mobile device, e.g., a smartphone device or a key fob device. The user may be in a moving vehicle or in some instances, the user may be riding a motorcycle or a bicycle. Further, consider the mobile device includes a tilt sensor, a small, low-power component configured to sense one or more tilts of the mobile device, including various orientations, inclinations, angles, and/or gradients of the mobile device. For example, the mobile device may tilt, slope, and/or slant based on the movements of the vehicle or the user. As such, the tilt sensor may detect the user is in a moving car.

In some instances, the mobile device may detect various types of movements based on the tilt sensor, possibly utilizing the tilt sensor coupled with other components of the mobile device, as described herein. For example, the mobile device may detect a number of tilts, a degree of each tilt, a number of tilts that meet or exceed a tilt threshold, duration of tilts, and/or a number of tilt patterns based on the tilts detected, possibly associated with the moving vehicle described above. In some instances, the tilt sensor, possibly coupled with other components of the mobile device, may indicate a varying and/or fluctuating tilt of the mobile device based on the acceleration of the moving vehicle. As such, the tilt sensor, possibly coupled with the other components, may also indicate a velocity, an acceleration, a g-force, and/or a number of vibrations detected based on various types of movements of the mobile device and/or the moving vehicle, among a number of other possibilities. Notably, by determining such types of movements, the mobile device may determine user activities associated with the mobile device.

In some instances, the mobile device may manage and/or preserve power associated with scanning for signals of interest, such as wireless signals, beacon signals, signals that may include short-wavelength radio waves in approximately the 2.4 to 2.485 GHz range, among other types of possible signals of interest. As such, the signals of interest described herein should not be interpreted in any limiting way as they may include various types of wireless signals, communication signals, and/or electromagnetic waves. In some instances, the mobile device may terminate the scanning power by terminating scanning operations to help preserve the power levels of the mobile device. For example, terminating the scanning power may intelligently preserve power of the mobile device where the user may not be interested in scanning for the signals described above. For instance, considering the scenarios above, the user is probably not interested in scanning for signals in the areas that the moving vehicle passes as it moves. As such, the mobile device may terminate the scanning operations to preserve power in the mobile device. In yet another instance, the tilt sensor may be used to determine the mobile device has stayed in a given area (e.g., the mobile device has not moved) or has been moved to an area and/or an environment without any signals of interest. As such, the mobile device may terminate the scanning operations to preserve power in the mobile device.

Further considering the scenarios above, the mobile device may detect the vehicle has come to a stop, possibly based on one or more tilts detected by the tilt sensor. As such, the user may exit the vehicle and begin walking, possibly to go to a coffee shop. In such circumstances, the tilt sensor, possibly coupled with other components, may detect various types of tilts described above including, for example, one or more tilts associated with the user getting out of the vehicle carrying the mobile device and walking to the coffee shop. In particular, the tilt sensor may detect multiple tilts and/or patterns of tilts associated with the mobile device, possibly alternating and/or swinging tilts associated with the user's steps and/or strides. Further, the tilt sensor, possibly coupled with other components, may also detect an absence of such tilts based on the user arriving at the coffee shop. In various such circumstances, the mobile device may initiate scanning power to cause the mobile device to scan for one or more signals of interest, such as one or more beacon signals in the coffee shop environment, possibly as the user walks towards the coffee shop and/or arrives at the coffee shop. For example, the mobile device may detect the beacon and identify the beacon is configured to enable the purchase of a cup of coffee.

Considering the scenarios above, the mobile device may connect with a remote server in the backend infrastructure based on one or more signals of interest, such as the beacon signals detected at the coffee shop. As such, the mobile device may complete a transaction to purchase the cup of coffee by connecting with the remote server. In particular, the mobile device may determine one or more tokens to complete the transaction. In some instances, each token may correspond to a particular payment instrument or a payment account, such as a payment account associated with PayPal, Inc. of San Jose, Calif., USA. As such, the user may select a desired token displayed by the mobile device to complete the transaction. Notably, in some instances, the user may complete the transaction offline and update the user account at another time, possibly after establishing a connection with the remote server.

It should be noted that one or more tilt sensors may have a number of advantages over other components, such as conventional accelerometers, gyroscopes, and/or orientation sensors. For example, the tilt sensor is a low or zero power sensor, device, and/or instrument configured to detect tilts of the mobile device while also preserving power of the mobile device. Further, the tilt sensor may, in some instances, be smaller than the conventional components described above to save space, e.g., board space, in the mobile device. Yet further, the tilt sensor provides a high level of durability, particularly with being impermeable and resistant to wearing out. For example, the tilt sensors described herein may have lifetimes of detecting numerous tilts without degradation in detection quality. In addition, the tilt sensor may be an inexpensive component to help lower the costs of components to manufacture the mobile device.

FIG. 1A illustrates an exemplary system 100, according to an embodiment. As shown, the system 100, possibly referred to a mobile system 100, may take the form of a key fob device. Yet, the mobile system 100 may take the form of other devices as well. For example, the mobile system 100 may also take the form a smartphone device, a personal computer, a tablet computer, and/or a wearable computing device, among other possible computing devices.

As shown, the mobile system 100 includes a tilt sensor 102. The tilt sensor 102 may be cylindrical in shape with one end portion 104 and another end portion 106. For example, the tilt sensor 102 may have an approximate 2-6 millimeter diameter and approximately a 10-14 millimeter length. Further, the tilt sensor 102 may include an object 108 configured to move between the end portion 104 and the end portion 106. The object 108 may be a conductive mass, such as a rolling ball and/or a blob of a dense substance, such as mercury. As such, the position of the object 108 at the end portion 104 or at the end portion 106 may be detected to indicate one or more tilts of the mobile device 100.

It should be noted that the tilt sensor 102, the end portions 104 and 106, and the object 108 are provided for purposes of illustration and explanation. As such, the tilt sensor 102 shown in FIG. 1A and possibly the other figures throughout this disclosure may be enlarged for explanatory purposes. Thus, the illustrations and the explanations should not be taken as limiting. For example, the tilt sensor 103 may take a number of other shapes and further, the tilt sensor 102 may not include the object 108 to detect one or more tilts of the computing system 100. In particular, the tilts may be detected by other means as described or contemplated herein with other types of components.

FIG. 1B illustrates one or more tilt 110 associated with an exemplary system 100, according to an embodiment. As shown, the mobile system 100 may include a hole 107 configured to attach and suspend from a ring and/or a keychain ring. As such, in some instance, the system 100 may take the form of a key fob device, possibly hanging from the keychain ring, among other types of devices contemplated herein. Further, as shown, the one or more tilts 110 of the system 100 may cause the object 108 to move to the end portion 104, possibly based on one or more forces, such as gravity, inertia, centripetal forces, among other types of forces associated with the system 100. Notably, the end portion 104 may include two poles such that the position of the object 108 at the end portion 104 may electrically connect the two poles, thereby acting as a switch. As such, the one or more tilts 110 of the mobile system 100 may be detected accordingly.

FIG. 1C illustrates one or more other tilts 112 associated with an exemplary system 100, according to an embodiment. As shown, the hole 107 may be attached to the ring and/or the keychain ring discussed above. As such, the one or more other tilts 112 of the system 100 may cause the object 108 to move to the end portion 106, also possibly based on the one or more forces described above, such as gravity, inertia, centripetal forces, among other types of forces associated with the system 100. Notably, the end portion 106 may also include two poles such that the position of the object 108 at the end portion 106 may electrically connect the two poles, thereby acting as a switch. As such, the one or more tilts 112 of the mobile system 100 may be detected accordingly.

As noted, the tilt sensor 102 may detect a degree 111 of one or more tilts 110 and/or 112. For example, the tilt sensor 102, the object 108, and/or the end portions 104 and/or 106 may have conductive properties such that the position of the object 108 between the end portions 104 and 106 may vary a measurable capacitance. For instance, one or more of the end portions 104 and 106 may include a component, such as a capacitor, that indicates a varying capacitance based on the given position of the object 110 between the end portions 104 and 106. As such, the degree 111 of one or more tilts 110 and/or 112 may be measured to indicate a velocity, an acceleration, and/or a g-force of the mobile system 100, among the other forces of the system 100 contemplated herein.

For example, considering the scenarios above, the degree 111 of the tilt 110 and/or 112 may vary or fluctuate between 10 and 15 degrees, among other possible ranges, corresponding to the velocity and/or the acceleration of the moving vehicle carrying the mobile system 100. As noted, the system 100 may take the form of a key fob device hanging from an area and/or or a module (e.g., the ignition, the dashboard, and/or console) within the moving vehicle. As such, the system 100 may determine and/or detect that it is being transported in the moving vehicle, thereby terminating scanning operations and scanning power, as described above. Further, the mobile system 100 may determine the vehicle has stopped and initiate the scanning power to resume scanning operations accordingly and perform a scan of the environment, in accordance with various operations described above.

In another example, a number of tilts 110 and/or 112 may be detected to meet or exceed a tilt threshold. For example, a series of the tilts 110 and 112 may include the tilt 110 followed by the tilt 112, and the tilt 112 followed by the tilt 110, and so on until the tilt threshold is met or exceeded. In some instances, meeting or exceeding the tilt threshold may indicate the user in possession of the mobile system 100 is walking in a given direction. In particular, the series of tilts 110 and/or 112 may correspond to steps and/or strides of the user walking, possibly if the system 100 takes the form the key fob device described above, possibly hanging on the user's clothing, for example. As such, considering the scenarios above, the mobile system 100 may provide scanning power to perform one or more scans of the environment. In addition, the mobile system 100 may also detect an absence of the tilts 110 and/or 112 to determine the user has arrived at a given destination, such as the coffee shop described above. As such, the mobile system 100 may provide the scanning power to perform the one or more scans, possibly to detect a signal of interest. As noted, the system 100 may detect the beacon signal at the coffee shop that enables the user to get cup of coffee with the mobile system 100.

FIG. 1D illustrates an exemplary system 100, according to an embodiment. As shown, the mobile system 100 may also include one or more processors 114 coupled to the tilt sensor 102. Further, the processor 116 may be coupled to the transceiver 116 with a connection, such as a universal asynchronous receiver/transmitter (UART) and/or a serial peripheral interface (SPI) connection. The processor 114 may interpret the pattern of tilt events and/or the degree 111 of one or more of the tilts 110 and/or 112 to determine the mobile system 100 is in a moving vehicle, and/or possibly sitting on the user's counter, among other possibilities.

As such, the processor 114 may terminate scanning power to the transceiver 116. Yet further, the processor 114 may determine the number of tilts 110 and/or 112 described above meets or exceeds a tilt threshold to determine the mobile system 100 is in the possession of a user walking to a particular destination, as described above. In addition, the processor 114 may determine that the user that has reached the destination, possibly based on absence of the tilts 110 and/or 122 detected. In various such circumstances, the processor 114 may provide scanning power to cause the transceiver 116 to scan 118 an environment of the mobile system 100 for one or more signals of interest described above.

FIG. 1E illustrates an exemplary system 100, according to an embodiment. As shown, the mobile system 100 includes the processor 114 coupled to the tilt sensor 102. Further, the processor 114 is coupled to the transceiver 116 with a connection, such as the UART and/or SPI connection. Yet further, the processor 114 may be coupled to an accelerometer 120, possibly also including an inclinometer. In some instances, the processor 114 may detect motion based on tilt switch activity and then decide to activate and/or enable the accelerometer 120 to provide additional movement data. This additional movement data may be interpreted to indicate speeds and/or velocities of the mobile system 100. For example, referring back to the scenarios above, the movement data may indicate speeds of the moving vehicle carrying the mobile system 100 ranging from 5 to 65 miles per hour, or possibly other ranges as well. Further, the movement data may indicate changes in such speeds, the rate of change in the speeds (e.g., the coordinate acceleration), and/or speed thresholds that may be exceeded. As such, the processor 114 may determine the mobile system 100 is in a moving vehicle or a stationary vehicle, possibly terminating the scanning power accordingly.

The accelerometer 120 may also provide movement data that indicates the proper acceleration, e.g., the g-force, of the mobile system 100. The movement data may also indicate the magnitude and the direction of the acceleration, possibly as a vector quantity. Further, the movement data may indicate various orientations of the mobile system 100 based on possible movement changes, vibrations, and/or shocks, possibly due to the user carrying the mobile system 100 while walking, as described above. The accelerometer 120 may take a variety of different forms such as a micro electro-mechanical system (MEMS), including a cantilever beam with a proof mass, also possibly referred to a seismic mass. In particular, the accelerations may be detected based on the proof mass deflecting from a neutral position in the accelerometer 120. In such instances, the deflections may be measured in analog or digital movement data.

In some embodiments, the processor 114 may activate or enable the accelerometer 120 based on a number of detections. As noted, the processor 114 may activate or enable the accelerometer 120 based on the one or more tilts 110 and/or 112 detected by the tilt sensor 102. Further, the one or more tilts 110 and/or 112 may act as a gating function and/or a trigger to provide the motion detecting power that activates the accelerometer 120. In some instances, additional circuitry may be activated to read the movement data from the accelerometer 120. As such, the accelerometer 120 may provide movement data indicating the mobile system 100 is moving in the moving vehicle, the system 100 is being carried by the user walking to the coffee shop, and/or the system 100 is attached to the user's clothing as the user is going for a jog, among other possible scenarios. As such, the processor 114 may determine various activities of the user based on the movement data from the accelerometer 120, possibly activities where movement data from the accelerometer 120 may not be necessary. Thus, the processor 114 may terminate the movement detection power to power down the accelerometer 120 and conserve power in the system 100 accordingly.

FIG. 2A illustrates timing diagrams 200 and 202, according to multiple embodiments. As shown, the timing diagram 200 includes a timeline 204 with a scan interval 208, a rest interval 210, and a scan interval 212, possibly associated with a passive mode (e.g., a passive scan mode) of the mobile system 100 described above. In some instances, the scan intervals 208 and/or 210 may each be time intervals of approximately five seconds in which the mobile system 100 provides scanning power to cause the transceiver 116 to scan an environment for one or more signals of interest, such as the beacon signals described above. Further, the rest interval 210 may be a time interval of approximately sixty seconds in which mobile system 100 terminates the scanning power, possibly to conserve power of the mobile system 100. As such, the scan interval 208 of approximately five seconds and rest interval 210 of approximately sixty seconds may reflect an approximate seven to eight percent duty cycle, among other possibilities.

As also shown, the timing diagram 202 includes a timeline 206 with the scan interval 208 described above, a rest interval 218, a scan interval 214, a rest interval 220, and a scan interval 216, possibly associated with an active mode (e.g., an active scan mode) of the mobile system 100 described above. In some instances, the scan intervals 208, 214, and/or 216 may each be time intervals of approximately five seconds in which the mobile system 100 provides scanning power to initiate scanning operations and cause the transceiver 116 to scan an environment. Further, the rest intervals 218 and/or 220 may be time intervals of approximately thirty seconds in which mobile system 100 terminates the scanning power and the scanning operations, possibly to conserve power of the mobile system 100. As such, the scan interval 208 of approximately five seconds and rest interval 218 of approximately thirty seconds may reflect a fourteen to fifteen percent duty cycle, among other possibilities.

As noted, referring back to FIGS. 1A-1E, the mobile system 100 includes the tilt sensor 102, one or more of the processors 114, and the transceiver 116. In one embodiment, the mobile system 100 also includes a non-transitory memory. As such, the one or more processors 114 may be coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the mobile system 100 to perform operations. The operations may include determining one or more tilts 110 and/or 112 of the computing system 100 detected by the tilt sensor 102. Notably, various patterns of the tilts 110 and/or 112 may also be determined.

Further, the operations may include determining the scan intervals 208, 214, and/or 216 and the rest intervals 218 and/or 220 based on the one or more tilts 110 and/or 112 of the mobile system 100 detected. For example, based on the one or more tilts 110 and/or 112, the system 100 may enter the active scan mode described above. Yet further, the operations may include providing scanning power to initiate scanning operations and cause the transceiver 116 to scan 118 an environment of mobile system 100, possibly to identify one or more signals of interest (e.g., beacon signals) based on the scan intervals 208, 214, and/or 216, and the rest intervals 218 and/or 220. In addition, the operations may include identifying the one or more signals of interest and/or the beacon signals from the scan 118 of the environment.

In some embodiments, the operations may include terminating the scanning power based on the one or more signals of interest identified. Yet, it should be noted that the operations may include determining that the one or more signals of interest, such as the beacon signals, are not identified in the environment. For example, the one or more beacon signals may not be identified from the scan 118 made during the scan intervals 208, 214, and/or 216. As such, the operations may include terminating the scan power and the scanning operations based on the one or more beacons not identified.

Yet further, in some embodiments, the mobile system 100 may identify the signals of interest from the scan 118 made during the scan intervals 208, 214, and/or 216. In some instances, the mobile system 100 may perform additional scans based on one or more beacons identified from the scan 118. For example, the operations described above may also include the mobile system 100 providing the scanning power to initiate the scanning operations and causing the transceiver 116 to further scan the environment for one or more additional beacons based on the one or more beacons identified from the scan 118. In particular, the one or more beacons identified from the scan 118 may not include a particular beacon that the user may be interested in. As such, the transceiver 116 may further scan the environment for the one or more additional beacons. Further, the system 100 may terminate the scanning power and the scanning operations based on a completion of the scan 118 for the one or more additional beacons to preserve power in the system 100.

In some embodiments, the mobile system 100 may receive user inputs. For example, the operations of the mobile system 100 described above may include receiving one or more user inputs from a user interface of the mobile system 100, possibly instructing the mobile system 100 to initiate a scan. Further, the mobile system 100 may receive one or more user inputs that indicate the user is not interested in one or more of the signals and/or beacons already identified from a previous scan. As such, the mobile system 100 may provide the scanning power to initiate scanning operation and cause the transceiver 116 to further scan the environment for one or more additional signals of interest based on one or more user inputs. Notably, the one or more user inputs received may also instruct the mobile system 100 to terminate the scanning power. As such, the mobile system 100 may terminate the scanning power and the scanning operations based on the one or more user inputs received.

In some embodiments, the mobile system 100 may determine a signal of interest, such as a recognized signal and/or a beacon. For example, the operations of the mobile system 100 described above may include determining a recognized signal from the one or more signals identified based on the scan 118. In particular, the recognized signal may correspond to scan data, e.g., signal and/or beacon data, stored by the mobile system 100. For example, the scan data may have been stored based on prior scans and prior signals and/or beacons identified. Further, the mobile system 100 may terminate the scanning power and the scanning operations based on the recognized beacon. Considering the scenarios above, for instance, the recognized beacon may be associated with the coffee shop such that the user may purchase the cup of coffee. As such, the mobile system 100 may terminate the scanning power based on the recognized beacon identified from the coffee shop.

Referring back to FIGS. 1A-1E, the mobile system 100 may activate the accelerometer 120, possibly based on the one or more tilts 110 and/or 112 detected by the tilt sensor 102. For example, the operations of the mobile system 100 described above may include providing movement detection power to initiate movement detection operations and activate the accelerometer 120 accordingly. As such, the mobile system 100 may retrieve movement data from the accelerometer 120. As noted, the movement data may correspond to various types of movements of the mobile system 100 detected by the accelerometer 120. In some instances, the operations may include determining the movement of the mobile system 100 meets or exceeds a movement threshold based on the movement data and/or the one or more tilts 110 and/or 112. Considering the scenarios above, for instance, the mobile system 100 may determine the movement meets or exceeds a speed threshold of five to ten miles per hour, possibly indicating the user is in a moving vehicle or is riding a bicycle. As noted, the scanning power may be terminated since the user is likely not interested in beacons in areas the user passes in the moving vehicle. Further, the operations may include terminating the movement detection power based on the movement determined that meets or exceeds the movement threshold to preserve power in the mobile system 100.

In some instances, the scan interval 208 and the rest interval 210 may be determined by the mobile system 100 based on meeting or exceeding the movement threshold described above. For example, the mobile system 100 may enter the passive mode, described above as the passive scan mode, to perform the scan 118. As such, the mobile system 100 may provide the scanning power to initiate scanning operations and cause the transceiver 116 to scan 118 the environment based on the scan intervals 208 and/or 212, and the rest interval 210. Thus, the power in the mobile system 100 may be preserved accordingly.

In some embodiments, the mobile system 100 may determine a user activity. For example, the operations of the mobile system 100 described above may include providing movement detection power to initiate movement detection operations to retrieve movement data from the accelerometer 120. As noted, the movement data may correspond to various movements of the mobile system 100 detected by the accelerometer 120. As such, the operations may include determining a user activity, such as the user sitting, standing, talking, eating, walking, and/or jogging, among other possible activities. Yet further, a given state of the mobile system 100 may also be determined. For example, it may be determined that the mobile system 100 is in a stationary state, possibly sitting on the user's counter. As such, various user activities and/or states associated with the mobile system 100 may be determined based on the movement data. Thus, the movement detection power may be terminated once the user activity is determined. For example, the system 100 may determine low or no user activity based on the system 100 detecting a stationary state on the user's counter. As such, the movement detection power may be terminated accordingly.

In some instances, the scan intervals 208, 214, and/or 216 and the rest intervals 218 and/or 220 in the timing diagram 202 may be determined by the mobile system 100 based on the user activity determined. For example, the mobile system 100 may enter an active mode to perform the scan 118, possibly based on the user activity determined. As such, the mobile system 100 may provide the scanning power to initiate scanning operations and cause the transceiver 116 to scan 118 the environment based on the scan intervals 208, 214, and/or 216 and the rest intervals 218 and/or 220.

FIG. 2B illustrates timing diagrams 230 and 232, according to multiple embodiments. As shown, the timing diagram 230 includes a timeline 234 with a scan 238, a rest interval 240, and a scan 242, possibly associated with a passive mode of the mobile system 100, as described above. In particular, the scan 238 may correspond to the scan interval 208 and the scan 242 may correspond to the scan interval 212 described above in relation to FIG. 2A.

As such, the scans 238 and/or 242 may each correspond to time intervals of approximately five seconds in which the mobile system 100 provides scanning power to initiate scanning operations and cause the transceiver 116 to scan the environment. Further, the rest interval 240 may be a time interval of approximately sixty seconds in which mobile system 100 terminates the scanning power, possibly to conserve power of the mobile system 100.

As shown, the timing diagram 232 includes a timeline 236 with the scan 238, a rest interval 252, a scan 244, a rest interval 254, a scan 246, a rest interval 256, a scan 248, a rest interval 258, and a scan 250, possibly associated with the passive mode, referred to as the passive scan mode above, and/or a back-off scan mode of the mobile system 100.

As noted, the timing diagram 232 includes the scan 238 from the timing diagram 230. Further, the scans 244, 246, 248, and/or 250 may be similar to the scan 238, possibly also corresponding to the scan intervals 208 and/or 212 described above in relation to FIG. 2B. Yet, the rest intervals 252, 254, 256, and/or 258 may each illustrate an exponential growth on the timeline 236. For example, the time interval 254 may be exponentially longer than the time interval 252. Further, the time interval 256 may be exponentially longer than the time interval 254. Yet further, the time interval 258 may be exponentially longer than the time interval 256, and so on.

In some embodiments, the operations of the mobile system 100 described above may include determining the number of scans 238, 244, 246, 248, and/or 250. Further, a number of rest intervals 252, 254, 256, and/or 258 may also be determined, possibly based on the one or more signals of interest identified from the scan 118. As noted, each subsequent rest interval from the number of rest intervals 252, 254, 256, and/or 258 may be exponentially longer than its previous rest interval. As such, the operations may also include providing scanning power to initiate scanning operations and cause the transceiver 116 to scan 118 the environment based the number of scans 238, 244, 246, 248, and/or 250, and the number of rest intervals 252, 254, 256, and/or 258. As such, the power of the mobile system 100 may be preserved accordingly.

FIG. 3A illustrates an exemplary system 300, according to an embodiment. As shown, the system 300, possibly referred to as a mobile system 300, may take the form of the mobile system 100 described above. For example, the tilt sensor 302 may take the form of the tilt sensor 102, the one or more processors 314 may take the form of the one or more processors 114, the transceiver 316 may take the form of the transceiver 116, and the hole 307 may take the form of the hole 107, as described above. As shown, the mobile system 300 may be located in one or more areas shown by the map 320 for illustrative purposes. For example, the mobile system 300 may be located in an environment 322 with the buildings 324, 326, 328, and/or 330. In particular, the mobile system 300 may be located at a position and/or a location 332 shown in the building 328.

In some embodiments, the tilt sensor 302 may detect one or more tilts 310 and/or 312 that may take the form of the tilts 110 and/or 112, respectively, as described above. Yet further, the respective degrees of the tilts 310 and/or 312 may vary or fluctuate between (plus or minus) 1 and 10 degrees, among other degrees and/or ranges of degrees contemplated herein. As such, the tilt sensor 302 may detect one or more tilts 310 and/or 312, one or more patterns of the tilts 310 and/or 312, and/or an absence of the tilts 310 and/or 312, among other detections related to the one or more tilts 310 and/or 312 described herein. Thus, in some instances, the one or more processors 314 may provide scanning power to initiate scanning operations and cause the transceiver 316 to scan 318 for one or more signals of interest in the environment 322, such as the beacon signals described above.

As shown, the scan 318 may extend up to a given distance 334 and/or cover a given scan environment 336. Notably, the scan distance 334 may be shortened to preserve power of the computing system 300, thereby covering a smaller scan environment 336. Yet, in some instances, the scan distance 334 may be extended to longer distances, thereby covering a larger scan environment 336, possibly for one or more periods of time. Thus, the scan 318 may pick up one or more signals of interest, such as beacon signals generated from the building 328 and/or generated from one or more beacon transmitters in the building 328. Further, the one or more processors 314 may terminate the scanning power to preserve power in the mobile system 300.

In some embodiments, the non-transitory machine-readable medium described above may cause the mobile system 300, also referred to as the mobile device 300, to perform additional operations. For example, the mobile device 300, may determine the one or more tilts 310 and/or 312 of the mobile device 300 detected by the tilt sensor 302 correspond with one or more tilt patterns of the mobile system 300. In some instances, the one or more tilt patterns may be determined based on the tilt sensor 302 detecting the tilt 310, the tilt 312, the tilt 310, and the tilt 312, among other patterns of described herein.

In some embodiments, referring also to FIG. 2B, the mobile device 300 may determine a scan interval 238 and a rest interval 240 based on the one or more tilts 310 and/or 312 that meet or exceed the tilt threshold. Further, the mobile device 300 may provide the scanning power to initiate scanning operations and cause the transceiver 316 to scan 318 the environment 336 of the mobile device 300 for one or more signals of interest based on the scan 238 and the rest interval 240, as shown in the timing diagram 230. Yet further, the mobile device 300 may terminate the scanning power based on a completion of the scan 318.

Further, consider a scenario such that the building 328 is the user's home. As such, the user may pick up the mobile device 300 from the counter in the user's home, possibly where the mobile device 300 may have been stationary. The one or more tilts 310 and/or 312 may cause the mobile device 300 to enter a given scan mode, possibly a given scan mode selected from a number of different scan modes associated with one or more power supplies of the mobile device 300. For example, the mobile device 300 may enter the scan mode to cause the transceiver 316 to initiate the scan 318 the environment 336 based on the scan interval 238 and the rest interval 240 determined from the scan mode selected. Further, the scan mode selected may be associated with a number of other scans and rest intervals, such as, the scans 238, 244, 246, 248, and/or 250, and the rest intervals 252, 254, 256, and/or 258, as described above.

In some embodiments, referring back to FIG. 2A, the mobile device 300 may determine one or more second tilts 310 and/or 312 detected by the tilt sensor 302, possibly during the scan interval 208. As such, the mobile device 300 may detect movement, possibly based on the user carrying the mobile device 208 to the building 328. In such instances, the mobile device may determine a second rest interval 210 based on the one or more second tilts 310 and/or 312 detected during the scan interval 208. As such, the mobile device 300 may terminate the scanning power for the second rest interval 210. In the example above, it should be noted that the mobile device 302 may perform the scan 318 and determine whether the tilts 310 and/or 312 are detected during the scan interval 208.

In some embodiments, the mobile device 300 may calculate a duration for the second rest interval 210 based on the one or more second tilts 310 and/or 312 detected, the scan 318, and/or the one or more signals of interest detected. For example, the mobile device 300 may calculate a longer duration for the second rest interval 210 based on the one or more tilts 310 and/or 312 detected, possibly indicating the mobile device 300 is in motion to a location, such as the building 328 described above. Yet, the mobile device 300 may calculate a shorter duration for the second rest interval 210 based on the scan 318 and/or one or more signals of interest detected, possibly to scan 318 the environment 336 for additional signals of interest.

In another example, consider a scenario such that the building 328 is a merchant store, possibly referred to as the merchant store 328. As such, the mobile device 300 may identify the one or more signals of interest from the scan 318 of the environment 336 for the scan interval 208. Further, the mobile device 300 may determine a time interval 218 without any user inputs associated with the one or more signals identified, possibly indicating that the user is not interested in the signals identified. Thus, the mobile device 300 may provide the scanning power to initiate scanning operations and cause the transceiver 316 to further scan 318 the environment 336 for one or more additional signals of interest based on the time interval 218 without any user inputs. In particular, the mobile device 300 may cause the transceiver 316 to scan 318 for the second scan interval 214.

In some embodiments, the mobile device 300 may identify the one or more signals of interest from the scan 318 of the environment 336. In some instances, the mobile device 300 may determine a recognized signal (e.g., a recognized beacon signal) in the one or more signals identified. For example, the recognized signal may correspond to data stored by the mobile device 300, possibly stored based on prior scans and/or signals identified. As such, the mobile device 300 may terminate the scanning power based on the recognized signal. In particular, the recognized signal may be associated with the merchant store 328 such that the user may purchase one or more items from the merchant store 328.

In some embodiments, the mobile device 300 may identify the one or more signals from the scan 318 of the environment 336. The mobile device 300 may determine the time interval 218 without any user inputs associated with the one or more signals identified, possibly indicating the user in not interested in the signals identified. Thus, referring back to FIG. 2B, the mobile device 300 may determine the number of scans 238, 244, 246, 248, and/or 250 shown in the timing diagram 232. Further, the mobile device 300 may determine the number of rest intervals 252, 254, 256, and/or 258 based on the time interval 218 without any user inputs. As noted, each subsequent rest interval from the number of rest intervals 252, 254, 256, and/or 258 may be exponentially longer than its previous rest interval. Thus, the mobile device 300 may provide the scanning power to initiate scanning operations and cause the transceiver 316 to scan 318 the environment 336 based on the number of scans 238, 244, 246, 248, and/or 250, and the number of rest intervals 252, 254, 256, and/or 258. As such, providing scanning power in the manner described above may preserve power in the computing device 300.

FIG. 3B illustrates the exemplary system 300, according to an embodiment. The system 300, possibly referred to as the mobile system 300, may include the tilt sensor 302, the one or more processors 314, and the transceiver 316, as described above in relation to FIG. 3A. Further, as shown, the mobile system 300 may include a user interface 340, fingerprint sensor 342, and a hole 307, as illustrated in an isometric view of the system 300. Notably the hole 307 may take the form of the hole 107 described above such that the hole 307 is configured to attach and suspend from a ring and/or a keychain ring. Considering the one or more scenarios described above, the mobile system 300 may be located in one or more areas shown by the map 320, such as in the location 332 shown in the merchant building 328, possibly including the coffee shop described above. Thus, the merchant building 328 may also referred to as the merchant terminal 328.

Further, consider a scenario where the user is carrying the mobile device 300 to purchase a cup of coffee at the merchant terminal 328. As such, the mobile device 300 may detect one or more tilts 310 and/or 312, a pattern with the one or more tilts 310 and/or 312, and/or a threshold met with the one or more tilts 310 and/or 312, among other possibilities. In some instances, the mobile device 300 may also detect an absence of the one or more tilts 310 and/or 312. As such, the mobile device 300 may provide the scanning power to initiate scanning operations and cause the transceiver 316 to scan 318 the environment 336, possibly to detect one or more signals of interest. For example, the one or more signals detected may cause the user interface 340 to display a request to purchase a cup of coffee at the merchant terminal 328. As such, the user may provide one or more user inputs to the user interface 348 indicating that she would like to purchase the cup of coffee, the type of coffee, and/or the size of the coffee, among other details associated with the cup of coffee desired.

As such, the mobile device 300 may receive the one or more inputs from the user interface 348. Further, the one or more inputs may indicate a selection from various front end tokens 350, 352, 354, and/or 356 to purchase the cup of coffee. For example, the front end token (FET) 350 may be associated with one or more payment services 360 provided by PayPal, Inc. of San Jose, Calif., USA. The FET 352 may be associated with a debit and/or a credit card 362 provided by Visa, Inc. of Foster City, Calif., USA. The FET 344 may be associated with a debit and/or a credit card 364 provided by MasterCard Incorporated of Purchase, N.Y., USA. The FET 356 may be associated with a transit card 366 provided by one or more transit providers.

In some embodiments, with a selection of the FET 350, the cup of coffee may be purchased with the service 360. Further, with a selection of the FET 352, the cup of coffee may be purchased with the card 362. Yet further, with a selection of the FET 354, the cup of coffee may be purchased with the card 364. As such, the selections of the FETs 350, 352, and/or 354 may enable the corresponding service 360, the card 362, and/or the card 364, respectively, to make purchases of various items. Notably, the cup of coffee is provided in the examples above for purposes of illustration and explanation, as other items and/or services may be purchased as well. As demonstrated above, the tokens 350-356 may be selected and/or controlled at the point of sale and/or the merchant terminal 328.

In some embodiments, the selection of the FETs 350-356 may be authenticated with biometric data. For example, the selection may be authenticated with fingerprint data received by the fingerprint sensor 342. In particular, based on the mobile device 300 receiving authentic fingerprint data from the fingerprint sensor 342, the mobile device 300 may determine the selection of the FETs 350-356 to complete the purchase of the cup of coffee in the scenarios above. Yet, under other circumstances, the mobile device 300 may provide various forms of data based on receiving the authentic fingerprint data. For example, the mobile device 300 may have driver's license data including the driver's license number and/or picture. Further, the mobile device 300 may have passport data including the passport number and/or picture. As such, based on receiving the fingerprint data, the driver's license data and/or the passport data may be provided by the device 300.

In some embodiments, the mobile device 300 may be referred to as a key fob system 300. As noted, the key fob system 300 may include the user interface 340 with touch sense capabilities and the fingerprint sensor 342. Further, the key fob system 300 may include a non-transitory memory and one or more hardware processors, such as the processor 114 described above in relation to FIGS. 1A-1E. As such, the one or more hardware processors 114 may be coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the key fob system 300 to perform operations. In particular, the key fob system 300 may detect one or more signals associated with an environment 336 of the key fob system 300, illustrated with a given distance and/or radius 334. The key fob system 300 may also display a request on the user interface 340 to select a token from a number of tokens 350-356 based on the one or more signals detected. The key fob system 300 may also determine a selection of the token 350 from the number of tokens 350-356 based on an input received with the user interface 340, possibly a touch input received with the user interface 340. The key fob system 300 may also authenticate the selection of the token 350 based on fingerprint data received with the fingerprint sensor 342.

In some embodiments, the key fob system 300 may include a tilt sensor 302. As such, the key fob system 300 may detect one or more tilts 310 and/or 312 of the key fob system 300 with the tilt sensor 302. Further, the key fob system 300 may scan the environment 336 of the key fob system 300 based on the one or more tilts 310 and/or 312 detected. As such, the one or more signals may be detected based on scanning the environment 336.

In some embodiments, the key fob system 300 may include the accelerometer 120 described above in relation to FIGS. 1A-1E. As such, the key fob system 300 may detect one or more movements of the key fob system 300 with the accelerometer 120. The key fob system 300 may also scan the environment 336 of the key fob system 300 based on the one or more movements detected. As such, the one or more signals may be detected based on scanning the environment 336.

In some embodiments, as noted, the key fob system 300 may be configured to scan for one or more signals. Further, the key fob system 300 may include a body structure 358 that includes one or more front surfaces 370 and one or more back surfaces 372. The one or more front surfaces 370 may be configured to house and/or hold the user interface 340 and the fingerprint sensor 342. The one or more back surfaces 372 may include one or more curvilinear surfaces, possibly one or more ergonomic surfaces configured to fit in a human hand. Further, the key fob system 300 may include the hole 307 that extends from the one or more front surfaces 370 to the one or more back surfaces 372, where the hole 307 is configured to suspend and/or hang the key fob system 300 from a keychain. Further, the key fob system 300 may include the tilt sensor 302 configured to detect one or more tilts 310 and/or 312 of the key fob system 300 based on the hole 307 suspending the key fob system 300 from the keychain.

FIG. 4 illustrates an exemplary method 400, according to an embodiment. Notably, one or more steps of the method 400 described herein may be omitted, performed in a different sequence, and/or combined with other methods for various types of applications contemplated herein.

As shown, at step 402, the method 400 may include determining one or more tilts detected by a tilt sensor of the mobile device meets or exceeds a tilt threshold. For example, the method 400 may include the mobile device 100 determining one or more tilts 110 and 112, the one or more tilts 310 and 312, and/or a combination of such tilts detected by the tilt sensor 102 of the mobile device 100 that meets or exceeds the one or more tilt thresholds as described herein. In some instances, a number of the one or more tilts 110, 112, 310, and/or 312 may meet or exceed the tilt threshold, possibly indicating an increase in movement of the mobile device 100. Yet further, the number of the one or more tilts 110, 112, 310, and/or 312 may meet or fall below the tilt threshold, possibly indicating a decrease in movement of the mobile device 100.

At step 404, the method 400 may include determining a number of scans and a number of rest intervals based at least on the one or more tilts that meet or exceed the tilt threshold. For example, the method 400 may include the mobile device 100 determining a number of scans 208, 214, and/or 216 based on the one or more tilts 110, 112, 310, and/or 312 described above that meet or exceed the tilt threshold. Yet further, the method 400 may include the mobile device 100 determining a number of rest intervals 218 and/or 220 based on such tilts 110, 112, 310 and/or 312 that meet or exceed the tilt threshold.

For example, the mobile device 100 may scan 118 the environment based on one or more of the scans 208, 214, and/or 216, and/or the one or more of the rest intervals 218 and/or 220.

At step 408, the method 400 may include terminating the scanning power based at least on the number of scans of the environment. For example, the method 400 may include terminating the scanning power based on a completion of the number of scans, such as the scan 208, 214, and/or 216, among various combinations of such scans.

In some embodiments, the method 400 may include the mobile device 100 providing movement detection power to initiate movement detection operations, possibly to retrieve movement data from the accelerometer 120 of the mobile device 100 that corresponds to movement of the mobile device 100 detected by the accelerometer 120. The method 400 may also include the mobile device 100 determining a user activity, such as the user sitting, standing, walking, jogging, riding a bike, riding a bus, driving a car, among other possible user activities. In particular, the mobile device 100 may determine the user activity associated with the mobile device 100 based on the movement data. As such, the number of rest intervals 218 and/or 220, including the durations of the rest intervals 218 and/or 220, may be calculated based on the various user activities. As such, the method 400 may also include terminating the movement detection power based on the user activity determined.

In some embodiments, the method 400 may include the mobile device 100 providing movement detection power to retrieve movement data from the accelerometer 120 of the mobile device 100. Referring back to FIGS. 2A-2B, the method 400 may include the mobile device 100 determining one or more time intervals 208, 214, 216, 218, and/or 220 without one or more movements of the mobile device 100 based on the movement data. The method 400 may include terminating the movement detection power based on the one or more time intervals 208, 214, 216, 218, and/or 220 without the one or more movements of the mobile device 100. Further, the scanning power may also be terminated based on terminating the movement detection power, possibly to further preserve power in the mobile device 100.

In some embodiments, the method 400 may include the mobile device 100 determining a trigger 222 that causes the transceiver 116 to scan the environment for the one or more scan intervals 214 and/or 216. For example, the trigger 222 may cause the transceiver 116 to scan 118 based on one or more signals of interest identified in the wireless environment. Further, the trigger 222 may cause the transceiver 116 to scan 118 based on motion detected by the tilt sensor 102 and/or the accelerometer 120. Yet further, the trigger 222 may cause the transceiver 116 to scan based on one or more user inputs received. As described above in relation to FIG. 3B, consider the mobile device 100 takes the form of the mobile device 300. As such, the one or more user inputs may be received from the user interface 340 and/or the fingerprint sensor 342. As such, the trigger 222 may be based on the one or more user inputs to cause the transceiver 316 to scan the location 332 of the mobile device 300 at the merchant store and/or terminal 328, among other possibilities.

In some embodiments, the method 400 may include determining a second number of scans 238, 244, 246, 248, and/or 250 based on the one or more signals of interest identified. Further, the method 400 may include determining a second number of rest intervals 252, 254, 256, and/or 258 based on the one or more signals identified from the scan 118. As noted, each subsequent rest interval from the number of rest intervals 252, 254, 256, and/or 258 may be exponentially longer than its previous rest interval. Further, the method 400 may include providing the scanning power to cause the transceiver 116 to scan the environment based the second number of scans 238, 244, 246, 248, and/or 250, and the second number of rest intervals 252, 254, 256, and/or 258.

FIG. 5 illustrates an exemplary system 500, according to an embodiment. The system 500 may include components from the systems 100 and/or 300 described above in relation to FIGS. 1A-4. As shown, for example, the system 500 may include a tilt sensor 502 that may take the form of the tilt sensors 102 and/or 302. Further, the system 500 may include one or more processors 504 that may take the form of the one or more processors 114 and/or 314. Yet further, the system 500 may include an accelerometer 520 that may take the form of the accelerometer 120. In addition, the system 500 may include a transceiver 516 that may take the form of the transceiver 116 and/or 316.

As illustrated, the one or more processors 504 may communicate with the communication chip 506 including the transceiver 516, possibly based on a UART or SPI connection. For example, the communication chip 506 may be a smart chip and/or a system-on-chip (SOC) configured to communicate in accordance with BLUETOOTH SMART protocols and/or BLUETOOTH LOW ENERGY protocols. In particular, the communication chip 506 may be a central and/or a hub that receives one or more signals of interest, such as the beacon signals described above. The communication chip 506 may be configured to communicate over the 2.4 to 2.485 GHz frequency range with ultra low-power consumption.

The one or more processors 504 may provide and/or terminate power in a number of ways, as described herein. For example, the one or more processors 504 may communicate with the communication chip 506 to initiate scanning operations and cause the transceiver 516 to scan for one or more signals of interests, such as the beacon signals described above, thereby causing the communication chip 506 to consume the scanning power. Further, the one or more processors 504 may communicate with the chip 506 to cause the transceiver 516 to stop scanning, thereby terminating the consumption of the scanning power. In some embodiments, the one or more processors 504 may provide the scanning power to the chip 506 to cause the transceiver 516 to scan for the one or more signals of interest, such as the beacon signals described above.
